CAST SKY: unify w. My Sky — inline --duoUser felt + scroll-snap wheel, gear NVM, burger reopen glow — TDD

Replaces the root-level dark Gaussian CAST SKY modal with the my_sky / sky.html
apparatus, mirroring the Sig Select unify (71c0069). Sky data stays seat-bound
(Character.seat), never a pos-circle.

- room.html: the sky overlay moves INTO .room-hex-pane on --duoUser felt
  (has-sky-stage), my_sea-style; rendered through the confirmed state too so
  the burger can reopen the saved wheel. Sky tooltips stay at root.
- _sky_overlay.html: drops .sky-backdrop / .sky-modal-wrap / .sky-modal / header
  + the in-felt NVM; reuses the shared .sky-page form/wheel (.sky-page--room).
  No live preview — the wheel only paints after SAVE SKY (my_sky parity); SAVE
  adds body.sky-saved → the felt flips to scroll-snap (form shunts to page 2,
  ease to the wheel on page 1). saved_sky_json primes the reopen draw. Inert
  STUB hook for the post-character-creation form lock (roadmap step 21).
- _sky.scss: in-room felt fill + open/close (html.sky-open); hides the position
  strip while the felt is up for a clean homogeneous surface.
- _room.scss: html.sky-open pins .room-aperture.is-scrollable (overflow hidden,
  snap none) so the ATLAS/SCROLL/YARN/POST/PULSE reelhouse is unreachable while
  casting; restored the instant the felt closes.
- _room_gear.html + room-views.js: NVM moves into a new .room-menu-sky gear pane
  (→ epic:room, which re-renders DRAW SEA if saved else CAST SKY); syncGear()
  shows it while sky-open.
- _burger.html + _burger.scss + burger-btn.js: the Sky sub-btn goes .active once
  saved (sky_btn_active = sky_confirmed) — concurrent w. a thrice --priTk burger
  pulse (.sky-saved-glow, rhymes w. .flash-inactive); an active click reopens
  the wheel via window.openSkyFelt.
- epic/views.py: sky_btn_active + saved_sky_json ctx off the seat's confirmed
  Character; the acting gamer's WS auto-reload is dropped (SAVE reveals the
  wheel in place; the gear NVM does the nav to DRAW SEA).
- Tests: PickSkyUnifiedFeltTest + PickSeaRenderingTest ITs (930 epic+gameboard
  green); BurgerSpec sky-glow/reopen Jasmine (full suite green); PickSky
  LocalStorageTest + PickSkyDelTest FTs reworked to the post-save flow.
